killing ants

Ants have reappeared in my kitchen and bathroom, and the occasional
one is seen near or on me as I sit in my chair. It's one of the signs
of spring.

I had a bad infestation of ants last year. Lasted from spring through
most of the summer. I laid barriers of baking soda by my kitchen
sink, the counter-tops all around and the baseboards. It worked well
by the baseboards. After pouring it all along the baseboards, the
ants stopped finding the cat food. That wasn't the case on the
counter-tops. They bothered me all summer there.

And that is what I am faced with now. My current technique to deal
with them is to wet a sponge, sweep them up with that and then rinse
the sponge under the faucet. This usually makes the ants fall into
the running water although sometimes I have to squeeze the sponge to
get them all out. The ants get washed down the drain in theory (out
of sight, out of mind being the rationale behind that) but many climb
back up out of the sink. I sweep them with a sponge again. And lately
I am thinking that my squeezing the sponge hard enough might kill
them or injure them. The temperature of the water too should be
considered. Too hot or cold will kill them,

It bothers me as I kill them. My heart feels a little ache each time
I do anything about it. I am intentionally killing them all. I don't
like that. When more come back again and again (different ants,
probably not the same ones) I get aggravated and sweep them up with
anger, feeling less guilty. But here I am, killing many live
creatures. The Jains don't like to kill germs. I don't like to kill
ants.

I probably will get some real toxic commercial spray since other
approaches haven't worked for me. I'll have to be careful it doesn't
harm the cat.

I guess I prefer to wash them down the drain because I am not
actually killing them then and there with that action. I am not
squishing each one. I am moving them somewhere else where, it
happens, they probably die. Some escape. Most die by drowning. Others
due to the temperature of the water. Others from whatever nastiness
is in the drain (chemicals, waste although ants can deal with some of
that stuff in their normal encounters in life.)

They don't scream. They do run away, sometimes. When I stand by the
sink or shower, at least when this started, they run away. Later on
in the summer, at least last summer, they didn't respond when I made
my presence known. I wonder why.
